Soo-saare Qiimo Fiican leh Aashitada Fosfooraska CAS:13598-36-2

sharraxaad gaaban:

Aashitada fosfooraska waa dhexdhexaad diyaarinta iskudhisyada kale ee fosfooraska. Aashitada fosfooraska waa walax ceeriin ah oo lagu diyaariyo fosfooraska daaweynta biyaha sida xakamaynta birta iyo manganese, joojinta iyo ka saarista miisaanka, xakamaynta daxalka iyo xasilinta koloriin. Cusbooyinka birta alkali (fosfooraska) ee aashitada fosfooraska ayaa si weyn loogu suuq geynayaa sidii fungicide beero (tusaale ahaan Downy Mildew) ama ilo sare oo nafaqada fosfooraska dhirta ah. Aashitada fosfooraska waxaa loo isticmaalaa dejinta isku darka walxaha balaastikada ah. Aashitada fosfooraska waxaa loo isticmaalaa in lagu xakameeyo heerkulka sare ee dusha sare ee birta u nugul daxalka iyo in lagu soo saaro saliidaha iyo waxyaabaha lagu daro saliidaha.

Sharaxaad

Asiidhka fosfooraska, H3PO3, waa diprotic (si fudud ayuu u ionizes laba protons), ma aha triprotic sida laga yaabo in lagu soo jeediyo qaacidadan. Asiidhka fosfooraska waa dhexdhexaad u ah diyaarinta iskudhisyada fosfooraska kale. Maadaama diyaarinta iyo isticmaalka "asiidhka fosfooraska" ay dhab ahaantii la xiriiraan tautomer-ka weyn, fosfoonikada, waxaa badanaa loogu yeeraa "asiidhka fosfooraska". Asiidhka fosfooraska wuxuu leeyahay qaacidada kiimikada H3PO3, kaas oo si fiican loogu muujiyo HPO(OH)2 si loo muujiyo dabeecaddiisa diprotonka.

Isticmaalka Aashitada Fosfooraska

1. Aashitada fosfooraska waxaa loo isticmaalaa in lagu soo saaro milixda bacriminta fosfooraska sida potassium phosphite, ammonium phosphite iyo calcium phosphite. Waxay si firfircoon ugu lug leedahay diyaarinta phosphites sida aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) iyo 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), kuwaas oo laga helo isticmaalka daaweynta biyaha sida miisaanka ama xakamaynta daxalka. Waxaa sidoo kale loo isticmaalaa falcelinta kiimikada sida wakiilka yareeya. Cusbo, phosphite-ka rasaasta waxaa loo isticmaalaa sidii xasiliye PVC ah. Waxaa sidoo kale loo isticmaalaa sidii horudhac diyaarinta phosphine iyo dhexdhexaad diyaarinta iskudhisyada kale ee fosfooraska.
2. Aashitada fosfoorasyada (H3PO3, aashitada orthophosphorous) waxaa loo isticmaali karaa mid ka mid ah qaybaha falcelinta ee isku-darka kuwan soo socda:
Asiidhyada α-aminomethylphosphonic iyada oo loo marayo Falcelinta Qaybaha Badan ee Mannich-Type
1-aminoalkanephosphonic acids iyada oo loo marayo amidoalkylation oo ay ku xigto hydrolysis
Asiidhyada α-aminophosphonic ee N-ilaaliya (phospho-isosteres ee amino acids dabiiciga ah) iyada oo loo marayo falgalka amidoalkylation
3. Isticmaalka warshadaha: Ururiyahan waxaa dhawaan la sameeyay waxaana loo isticmaalay inuu noqdo ururiyaha gaarka ah ee cassiterite laga soo bilaabo macdanta leh halabuurka gangue ee adag. Iyada oo lagu saleynayo fosfonic acid, Albright iyo Wilson waxay sameeyeen noocyo kala duwan oo ururiyayaal ah oo inta badan loogu talagalay sabbeynta macdanta oksaydhka (tusaale ahaan cassiterite, ilmenite iyo pyrochlore). Wax yar ayaa laga ogyahay waxqabadka ururiyayaashan. Daraasado kooban oo lagu sameeyay macdanta cassiterite iyo rutile ayaa muujiyay in qaar ka mid ah ururiyayaashu ay soo saaraan xumbo badan laakiin aad u xulasho badan.
